HV20822FG-G

Analog Switches - Special Purpose Overview

The HV20822FG-G is a high-voltage analog switch IC manufactured by Microchip Technology, housed in a 48-lead LQFP package. It integrates sixteen single-pole single-throw (SPST) switches organized into two independent sets of eight channels. The device operates with a positive supply voltage ranging from +50V to +110V and a negative supply voltage ranging from -10V to VPP minus 220V. The logic power supply accepts voltages between +4.75V and +12.6V. Typical on-resistance is 22Ω at +25°C under standard conditions, with a maximum turn-on and turn-off time of 5µs. Quiescent current consumption is typically 10µA.

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The M931 suffix indicates reel packing, while other suffixes may denote tray configurations. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing circuits requiring high-voltage analog signal switching controlled by low-voltage CMOS logic. Ensure the application voltage does not exceed the absolute maximum ratings of +225V across the supply rails. Verify that the thermal resistance characteristics of the 48-lead LQFP package are sufficient for the expected power dissipation in the target environment.

Analog Switches - Special Purpose Part Context

This part belongs to the HV20822 series of high-voltage analog switches originally developed by Supertex Inc., which was acquired by Microchip Technology. The series is designed to replace electromechanical relays in applications demanding compact size and high reliability. The FG designation specifically identifies the 48-lead LQFP package option within the product family.

Analog Switches - Special Purpose Replacement Considerations

Direct replacements include the HV20820FG-G for tray-packaged units or variants with different suffixes indicating alternative packing methods such as reels. Cross-referencing pinouts and electrical specifications is required when substituting with other high-voltage analog switches from different manufacturers.
